||
TEE2012_HadoopDemos | ||
This is a set of demos used at TechEd Europe 2012 | ||
|
||
Data Set assumptions | ||
=================== | ||
|
||
The bulk of these demos operate on a set of flight delay information, originally obtained from the Azure DataMarket (available here: https://datamarket.azure.com/dataset/e29b7fb9-3d2e-4f35-8088-c97dbd75cd1f) | ||

Basic Streaming | ||
====================== | ||
|
||
This is a sample of basic map reduce based streaming using the streaming jar. | ||
|
||
Streaming i | ||

||
Build Instructions | ||
====================== | ||
Build projects in VS | ||
|
||
or | ||
|
||
msbuild basicNetStreaming.sln | ||
|
||
should do the trick | ||
|
||
Execution Instructions | ||
====================== | ||
From a Hadoop command prompt (note, this assumes that %HADOOP_HOME% is defined, the streaming jar has been built, and a full path to the executables: | ||
|
||
hadoop jar %HADOOP_HOME%\lib\hadoop-streaming.jar -mapper f:\dev\src\csharp\hadoopdebugger\GenerateAirlineKeyMapper\bin\Debug\GenerateAirlineKeyMapper.exe -reducer f:\dev\src\csharp\hadoopdebugger\AirlineFlightCountReducer\bin\Debug\AirlineFlightCountReducer.exe -input fixed_flights -output test_streaming | ||
